Description
본 발명은 흙응결제 및 이를 이용한 흙포장공법에 관한 것으로, 보다 상세하게는 흙을 응집, 고결시켜 먼지 발생을 억제하고 질척거림을 방지하는 흙응결제 및 이를 이용한 흙포장공법에 관한 것이다.The present invention relates to a soil coagulant and a soil pavement method using the same. More particularly, the present invention relates to a soil coagulant for inhibiting dust generation by preventing agglomeration and solidification of soil and a soil pavement method using the same.
흙포장 도로를 조성할 때에는 흙을 결합시키면서 일정한 강도를 유지하기 위하여 결합제가 혼합되어 사용된다. 이 결합제는 흙과 물과 혼합되어 새로운 반응생성물을 흙속에 생성시켜 흙 입자 사이의 공극을 치밀하게 채워주거나 흙 입자 사이의 정전기적인 인력을 증진시켜 흙의 제 성질을 개선시킨다.When constructing a dirt road, a binder is mixed to maintain a constant strength while combining soil. The binder is mixed with soil and water to create new reaction products in the soil, which densely fills the voids between the soil particles or promotes electrostatic attraction between the soil particles, improving soil properties.
일반적으로 흙을 고화시키는 결합제로는 포틀랜트 시멘트, 슬래그 시멘트, 플라이애시 시멘트 등의 시멘트류가 사용되고 있다. 이는 적은 비용으로 흙을 고화시킬 수 있고 사용이 간단하기 때문이다. 그러나 이러한 시멘트류는 동결 융해에 의한 내구성 저하, 건조수축에 의해 균열이 발생하는 문제점이 있고 중금속이 용출될 위험성이 있다.In general, cements such as portland cement, slag cement, and fly ash cement are used as binders to solidify soil. This is because the soil can be solidified at a low cost and is simple to use. However, such cements have problems of cracking due to deterioration in durability due to freeze-thawing and dry shrinkage, and there is a risk of heavy metals eluting.
이에, 환경친화적인 흙고화용 결합제의 개발이 진행되고 있다. 한국특허 제 570958호(환경친화적이며, 속경성 및 고강도 특성을 가지는 흙포장용 조성물)와, 한국특허 제590392호(흙 고화재 및 이를 이용한 흙의 고화방법) 및 한국특허 제632705호(흙 고화포장 조성물과 이를 이용한 흙 고화포장공법) 등에 자연친화적이며 강도 높은 흙포장용 조성물 및/또는 흙고화재가 제시되어 있다. 그러나 상기한 흙포장용 조성물 및/또는 흙고화재는 다량의 시멘트를 원료로서 함유하고 있으므로 시멘트가 갖는 기존의 문제점을 해결하는데는 한계가 있었다. Therefore, the development of environmentally friendly binder for soil solidification is in progress.

본 발명의 흙응결제에 있어서, 규소화합물은 흙의 경화속도를 촉진시키는 역할을 하고 표면 코팅 효과가 있어 물의 침투 저항성을 향상시키게 된다. 흙응결제 총중량에 대하여 규소화합물의 함량이 50 중량% 미만이면 흙의 경화속도가 지연되는 문제가 있고 규소화합물의 함량이 60 중량%를 초과하면 타성분의 함량이 낮아짐으로써 입자의 응집 효과가 떨어지는 문제가 있다. In the soil coagulant of the present invention, the silicon compound serves to promote the curing rate of the soil and has a surface coating effect to improve the penetration resistance of water. If the content of the silicon compound is less than 50% by weight, the curing rate of the soil is delayed. If the content of the silicon compound is more than 60% by weight, the content of other components is lowered, so that the aggregation effect of the particles is lowered. There is.
본 발명의 흙응결제에서 바람직하게 사용되는 규소화합물은 SiO2 함량이 규소화합물 총중량에 대하여 20 내지 50 중량%이다. The silicon compound preferably used in the soil coagulant of the present invention has a SiO 2 content of 20 to 50% by weight based on the total weight of the silicon compound.
본 발명의 흙응결제에 있어서, 벤토나이트는 흙 입자와 흙응결제 입자 간의 증점 효과를 향상시키는 역할을 하는 것으로 입자들이 분리되지 않고 응집되도록 함으로써 윤활성, 미장성에 의해 작업성을 개선시킨다. 또한, 벤토나이트는 물을 흡착하여 팽윤한다. 흙응결제 충중량에 대하여 벤토나이트의 함량이 22 중량% 미만이면 작업성이 떨어지는 문제가 있고 벤토나이트의 함량이 35 중량%를 초과하면 경화속도가 지연되는 문제가 있다.In the soil coagulant of the present invention, bentonite serves to improve the thickening effect between the soil particles and the soil coagulant particles, thereby improving the workability by lubricity and plastering by allowing the particles to aggregate without being separated. Bentonite also swells by adsorbing water. If the content of bentonite is less than 22% by weight relative to the weight of the soil coagulant, there is a problem of poor workability, and when the content of bentonite exceeds 35% by weight, there is a problem that the curing speed is delayed.
본 발명의 흙응결제에 있어서, 바람직하게 사용되는 벤토나이트는 나트륨계 및 칼슘계로 이루어지는 군에서 적어도 하나 이상 선택되는 것이다.In the soil coagulant of the present invention, bentonite which is preferably used is selected from at least one selected from the group consisting of sodium and calcium.
본 발명의 흙응결제에 있어서, 증점제는 흙 입자와 흙응결제 입자의 점도를 향상시켜 입자들이 응집되어 접착되도록 함으로써 윤활성 및 작업성을 부여할 뿐만 아니라 건조 및 경화 재료에 대하여 보수성을 부여한다. 흙응결제 충중량에 대하여 증점제의 함량이 8 중량% 미만이면 입자간의 응집 효과가 떨어지는 문제가 있고 증점제의 함량이 20 중량%를 초과하면 경화속도가 지연되는 문제가 있다.In the soil coagulant of the present invention, the thickener improves the viscosity of the soil particles and the soil coagulant particles to agglomerate and adhere the particles, thereby providing lubricity and workability as well as conserving water for drying and curing materials.

본 발명의 흙응결제에 있어서, 바람직하게 사용되는 증점제는 전분계, 폴리사카라이드계, 셀룰로오즈계 및 아크릴계로 이루어지는 군에서 적어도 하나 이상 선택되는 것이다.In the soil coagulant of the present invention, the thickener used preferably is at least one selected from the group consisting of starch, polysaccharide, cellulose and acryl.
본 발명의 흙응결제는 상술한 구성성분이 상술된 비율로 이루어질 때 흙응결제로서 최대의 효능을 발휘한다.The soil coagulant of the present invention exhibits maximum efficacy as the earth coagulant when the above-mentioned components are made in the above-mentioned ratios.
본 발명의 흙응결제가 상술한 비율로 배합되어 물과 혼합되어 사용되는 것이 바람직하다. 흙응결제와 물의 배합비는 중량비를 기준으로 1 : 1 ~ 5가 바람직하다. 흙응결제와 물의 보다 바람직한 배합비는 중량비 기준으로 1 : 1.5 ~ 3이다.It is preferable that the soil coagulant of the present invention is blended in the above-mentioned ratio and used in admixture with water. The mixing ratio of the soil coagulant and water is preferably 1: 1 to 5 based on the weight ratio. The more preferable compounding ratio of the soil coagulant and water is 1: 1.5 to 3.
한편, 본 발명의 흙응결제는 흙응결제 총중량에 대하여 탄산칼슘 1 내지 10 중량%가 더 포함되어 이루어질 수 있다. 탄산칼슘은 액상을 안정화시키며 충전제 역할 및 표면 착색제 역할을 하는 것으로 표면 활성도를 증대시키고 작업성을 개량하는 효과가 있다. 탄산칼슘 1 중량% 미만으로 배합되면 작업성이 떨어지는 문제점이 있고, 10 중량%를 초과하여 배합되면 타성분의 함량이 낮아짐으로써 흙의 경화 속도가 지연되는 문제점이 있다.On the other hand, the soil coagulant of the present invention may be made by further comprising 1 to 10% by weight of calcium carbonate relative to the total weight of the soil coagulant. Calcium carbonate stabilizes the liquid phase and acts as a filler and a surface colorant, thereby increasing surface activity and improving workability. If the amount is less than 1% by weight of calcium carbonate, there is a problem that the workability is poor, and if the amount exceeds 10% by weight, the content of other components is lowered, thereby causing a delay in curing of the soil.
또한, 본 발명의 흙응결제는 흙응결제 총중량에 대하여 메타카올린 5 내지 15 중량%가 더 포함되어 이루어질 수 있다. 메타카올린은 카올린을 특수처리하여 흙과 혼화가 잘되도록 하는 혼화제로 에트린자이트를 형성하여 흙의 응집, 고결 능력을 증진시킴으로써 압축강도 및 내구성을 향상시킨다. 또한 메타카올린은 표면의 활성도를 증대시키고 작업성을 개량하는 효과가 있다. 메타카올린이 5 중량% 미만으로 배합되면 작업성이 떨어지는 문제점이 있고, 15 중량%를 초과하여 배합되면 타성분의 함량이 낮아짐으로써 흙의 경화 속도가 지연되는 문제점이 있다.In addition, the soil coagulant of the present invention may be made to further comprise 5 to 15% by weight metakaolin relative to the total weight of the soil coagulant. Metakaolin is an admixture that is specially treated with kaolin to make it well mixed with soil to form ethrinzite, thereby improving the compressive strength and durability by enhancing the cohesion and freezing ability of the soil. In addition, metakaolin has the effect of increasing the surface activity and improving workability. When the metakaolin is blended in less than 5% by weight, there is a problem of poor workability, and when it is blended in excess of 15% by weight, the content of other components is lowered, thereby delaying the curing rate of the soil.
또한, 본 발명의 흙응결제는 흙응결제 총중량에 대하여 석회 1 내지 10 중량%가 더 포함되어 이루어질 수 있다. 석회는 알칼리 자극제로 작용하는 것으로서 불투과성의 산화피막이 형성되어 수화반응이 중단되는 입자에 작용하여 산화피막을 파괴시키고 수화반응을 다시 진행시켜 강도를 증진시키는 역할을 한다. 또한 석회는 건조수축 방지 효과를 나타내며 흙포장의 포장면의 보습성을 유지하도록 하고 면을 잡는 작용도 한다.In addition, the soil coagulant of the present invention may be made by further comprising 1 to 10% by weight of lime relative to the total weight of the soil coagulant. Lime acts as an alkali stimulant, and an impermeable oxide film is formed to act on particles that stop the hydration reaction, thereby destroying the oxide film and proceeding the hydration reaction again to enhance strength. In addition, lime exhibits the effect of preventing dry shrinkage and maintains the moisturizing properties of the pavement surface of the soil pavement.
또한, 본 발명의 흙응결제는 흙응결제 총중량에 대하여 슬래그 1 내지 10 중량%가 더 포함되어 이루어질 수 있다. 슬래그는 잠재수경성을 갖고 있는 것으로 단독으로 반응하지 않으나 반응 및 자극제가 첨가되면 강도를 증진시키고 흙을 응집시키는 작용을 한다. 즉 수화시 수화광물인 에트린자이트를 형성하여 급속한 강도를 발현하게 된다.In addition, the soil coagulant of the present invention may be made to further comprise 1 to 10% by weight of slag relative to the total weight of the soil coagulant. The slag has latent hydrophobicity and does not react alone, but when the reaction and stimulant are added, the slag increases strength and aggregates soil. That is, when hydrated, ethrinzite, a hydrated mineral, is formed to express rapid strength.
또한, 본 발명의 흙응결제는 흙응결제 총중량에 대하여 석고 1 내지 10 중량%가 더 포함되어 이루어질 수 있다. 석고는 황산염 자극제로 작용, 반응시 생성되는 황산염을 자극하여 반응이 활발하게 일어나게 함으로써 수화를 촉진시켜 에트린자이트를 형성함으로써 흙포장재의 강도를 증진시킴은 물론 건조수축 방지 역할을 한다.In addition, the soil coagulant of the present invention may be made to further comprise 1 to 10% by weight gypsum relative to the total weight of the soil coagulant. Gypsum acts as a sulphate stimulant, stimulates the sulphate produced during the reaction to promote the hydration, thereby promoting hydration to form ethrinzite, thereby enhancing the strength of the soil pavement material, and also serves to prevent dry shrinkage.
또한, 본 발명의 흙응결제는 흙응결제 총중량에 대하여 황토 1 내지 10 중량%가 더 포함되어 이루어질 수 있다. 황토는 원적외선을 방사하여 인체에 이로울 뿐만 아니라 열전도율이 높아 지열의 발산이 적으며 강알칼리성을 약알칼리성으로 낮춰주는 효과가 있다. 또한 색질감이 뛰어나고 빛을 흡수하여 보행자에게 시각적으로 안정감을 줄 수 있다. In addition, the soil coagulant of the present invention may be made by further comprising 1 to 10% by weight ocher relative to the total weight of the soil coagulant. Ocher is not only beneficial to the human body by radiating far infrared rays, but also has high thermal conductivity, low geothermal heat emission, and has the effect of lowering strong alkalinity to weak alkalinity. In addition, it is excellent in color and absorbs light, giving visual stability to pedestrians.
또한, 본 발명의 흙응결제는 흙응결제 총중량에 대하여 유동화제 1 내지 2 중량%가 더 포함되어 이루어질 수 있다. 유동화제는 각 성분의 분산성을 향상시켜 혼합 효율을 높이며 포장체의 내구성을 향상시킨다. 이 유동화제는 리그닌계, 나프탈렌계, 멜라민계 및 폴리카본산계로 이루어지는 군에서 적어도 하나 이상 선택되는 것이 바람직하다.In addition, the soil coagulant of the present invention may be made of 1 to 2% by weight of the fluidizing agent based on the total weight of the soil coagulant.

이어, 포설된 흙을 전압다짐한다(1차 전압).Subsequently, the installed soil is compacted (primary voltage).
이어, 상기 전압된 흙 위에 앞서 물과 혼합된 흙을 포설한다(2차 포설).Subsequently, the soil mixed with water is laid on the voltaged soil (secondary laying).
이어, 2차 포설된 흙 위에 본 발명의 흙응결제를 적용한다. 이때 흙응결제는 물에 희석되어 사용되는 것이 바람직한데, 흙응결제와 물의 배합비는 중량비를 기준으로 1 : 1 ~ 5가 바람직하다. 흙응결제는 포설된 흙 위에 도포 또는 살포 등의 방법으로 적용되는 것이 바람직하다. 이때 물과 배합된 흙응결제는 흙 100 중량부에 대하여 5 내지 15 중량%가 사용되는 것이 바람직하다.Subsequently, the soil coagulant of the present invention is applied to the secondary soil. At this time, the soil coagulant is preferably used diluted in water, the mixing ratio of soil coagulant and water is preferably 1: 1 to 5 based on the weight ratio. The soil coagulant is preferably applied by a method such as coating or spraying on the installed soil. At this time, the soil coagulant blended with water is preferably used 5 to 15% by weight based on 100 parts by weight of soil.
이어, 흙응결제가 적용된 흙을 전압하는 공정을 시행한다(2차 전압).Subsequently, a process of voltage applying the soil coagulant is applied (secondary voltage).
이어, 크랙방지를 위하여 줄눈시공을 할 수 있다. 이는 온도와 습도에 따라 흙포장체가 팽창 또는 수축하게 되어 발생되는 크랙을 방지하기 위함이다. Then, joint construction can be performed to prevent cracking. This is to prevent cracks caused by the expansion or contraction of the soil package according to the temperature and humidity.
상기 단계를 거친후 선형잡기 및 마무리하고 건조, 양생시킨다.After the above steps, linear catching and finishing, drying and curing.
한편, 상기 혼합단계에서 석회, 슬래그, 석고 및 벤토나이트가 더 혼합되어 시공될 수 있다. 석회, 슬래그, 석고 및 벤토나이트의 혼합물은 결합제의 역할을 하는 것으로 이는 흙과의 결합성이 좋아 흙을 응집시키고 고결시킨다. 이때, 석회, 슬래그, 석고 및 벤토나이트의 혼합물이 흙 100 중량부에 대하여 5 내지 15 중량부 혼합되는 것이 바람직하다.Meanwhile, in the mixing step, lime, slag, gypsum and bentonite may be further mixed and constructed. A mixture of lime, slag, gypsum and bentonite acts as a binder, which binds to and solidifies the soil due to its good binding properties. At this time, the mixture of lime, slag, gypsum and bentonite is preferably mixed 5 to 15 parts by weight based on 100 parts by weight of soil.
상기한 결합제 투여시 흙의 응집, 고결 효과 상승 메카니즘을 보다 상세하게 설명한다.The mechanism of coagulation of soil and the effect of freezing effect upon administration of the binder will be described in more detail.
혼합단계에서 흙, 결합제 및 물을 혼합시키면 결합제의 수화반응으로 발생하는 열에 의해 수분을 증발시켜 흙 내의 수분을 감소시키며 다짐을 촉진하게 된다.Mixing the soil, the binder and water in the mixing step to evaporate moisture by the heat generated by the hydration of the binder to reduce the moisture in the soil and promote compaction.
CaO + H2O → Ca(OH)2 + 열CaO + H 2 O → Ca (OH) 2 + Heat
또한, 결합제 성분 중 칼슘 이온이 물에 분산되어 있는 흙 입자에 가해지면, 흙 입자 표면에 흡착되어 있던 Na+, K+, H+, Mg2+ 등이 Ca2+에 의하여 치환되는 이온교환반응이 일어난다. Ca(OH)2가 이온교환 용량 이상으로 가해지면 수산화이온(OH-)이 증가하여 물은 알칼리성이 되며 Ca2+는 더욱 다량으로 흡착된다. 이로 인하여 서로 반발하고 있던 흙 입자가 결합되어 커다란 덩어리가 되는 단결화가 일어난다.In addition, when calcium ions in the binder component are applied to the soil particles dispersed in water, the ion exchange reaction in which Na + , K + , H + , Mg 2+, etc. adsorbed on the soil particles surface is replaced by Ca 2+ This happens. When Ca (OH) 2 is added above the ion exchange capacity, hydroxide ions (OH − ) are increased so that the water becomes alkaline and Ca 2+ is adsorbed in a larger amount. This causes the soil particles that are repulsing to combine to form a large mass.
또한, 상기 결합제 성분 중 석회는 장기적으로 공기 중의 탄산과 반응하여 탄산칼슘(CaCO3)을 형성한다. 이 반응으로 알루민산칼슘과 탄산칼슘이 반응하여 흙을 응집고결시키는 작용을 한다. 석회는 이산화탄소를 석회석으로 고정시키고 탄산칼슘화가 진행되며 응집고결화가 촉진되어 흙포장체가 안정화된다.In addition, lime in the binder component reacts with carbonic acid in air for a long time to form calcium carbonate (CaCO 3 ). In this reaction, calcium aluminate and calcium carbonate react to agglomerate and solidify soil. Lime fixes carbon dioxide with limestone, promotes calcium carbonate, promotes coagulation, and stabilizes the soil package.
Ca(OH)2 + CO2 → CaCO3 + H2OCa (OH) 2 + CO 2 → CaCO 3 + H 2 O
특히 상기 혼합단계에서 석회, 슬래그, 석고 및 벤토나이트로 이루어지는 결합제가 혼합될 때에는, 상기 결합제는 생석회, 소석회 및 폐석회로 이루어지는 군에서 적어도 하나 이상 선택되는 석회 40 내지 55 중량%; 고로슬래그, 제강슬래그 및 비철슬래그로 이루어지는 군에서 적어도 하나 이상 선택되는 슬래그 30 내지 45 중량%; 천연무수석고, 알파형 반수석고, 인산석고 및 폐석고로 이루어지는 군에서 적어도 하나 이상 선택되는 석고 5 내지 15 중량%; 나트륨계 및 칼슘계로 이루어지는 군에서 적어도 하나 이상 선택되는 벤토나이트 1 내지 10 중량%로 이루어지는 것을 특징으로 한다.In particular, when the binder consisting of lime, slag, gypsum and bentonite is mixed in the mixing step, the binder is 40 to 55% by weight of at least one selected from the group consisting of quicklime, slaked lime and waste lime; 30 to 45 wt% of slag selected from the group consisting of blast furnace slag, steelmaking slag and non-ferrous slag; 5 to 15% by weight of at least one gypsum selected from the group consisting of natural anhydrite, alpha-type hemihydrate gypsum, phosphate gypsum and waste gypsum; At least one bentonite selected from the group consisting of sodium-based and calcium-based is characterized in that it comprises 1 to 10% by weight.
결합제 중 석회의 함량은 결합제 총중량에 대하여 40 내지 55 중량%가 바람직하다. 석회의 함량이 40 중량% 미만일 경우에는 소기의 응집력 및 강도 발현이 어려운 문제점이 있고, 석회 함량이 55 중량%를 초과하면 과팽창할 우려가 있다.The amount of lime in the binder is preferably 40 to 55% by weight based on the total weight of the binder. If the lime content is less than 40% by weight, there is a problem in that the desired cohesion and strength are difficult to develop, and when the lime content exceeds 55% by weight, there is a fear of overexpansion.
결합제 중 슬래그의 함량은 결합제 총중량에 대하여 30 내지 45 중량%가 바람직하다. 슬래그의 함량이 30 중량% 미만일 경우에는 강도 발현이 미비하고, 슬래그 함량이 45 중량%를 초과하면 타성분인 자극제의 양이 적어 흙의 응집이 잘 이루어지지 않는 문제점이 있다.The content of slag in the binder is preferably 30 to 45% by weight based on the total weight of the binder. When the content of slag is less than 30% by weight, the strength is insufficient, and when the content of the slag exceeds 45% by weight, there is a problem in that the aggregation of the soil is not good because the amount of other stimulants is small.
결합제 중 석고의 함량은 결합제 총중량에 대하여 5 내지 15 중량%가 바람직하다. 석고의 함량이 5 중량% 미만일 경우에는 소기의 강도 발현이 어려우며 건조수축 효과가 떨어지는 문제점이 있고, 석고 함량이 15 중량%를 초과하면 과팽창할 우려가 있다.The content of gypsum in the binder is preferably 5 to 15% by weight based on the total weight of the binder. When the content of gypsum is less than 5% by weight, there is a problem in that the desired strength is difficult to express and the dry shrinkage effect is reduced, and when the gypsum content exceeds 15% by weight, there is a fear of overexpansion.
결합제 중 벤토나이트의 함량은 결합제 총중량에 대하여 1 내지 10 중량%가 바람직하다. 벤토나이트의 함량이 1 중량% 미만일 때는 작업성이 떨어지는 문제점이 있고, 벤토나이트의 함량이 10 중량%를 초과하면 과도한 증점성으로 인한 재료 뭉침 현상이 일어나는 문제점이 있다. The content of bentonite in the binder is preferably 1 to 10% by weight based on the total weight of the binder. When the content of bentonite is less than 1% by weight, there is a problem in poor workability, and when the content of bentonite exceeds 10% by weight, there is a problem in that agglomeration of materials due to excessive thickening occurs.
또한, 상기 혼합단계에서 황토, 유동화제가 더 혼합되어 시공될 수 있다. 이때, 흙 100 중량부에 대하여 황토 1 내지 10 중량부 및 유동화제 1 내지 2 중량부가 혼합되는 것이 바람직하다. 상기 유동화제는 리그닌계, 나프탈렌계, 멜라민계 및 폴리카본산계로 이루어지는 군에서 적어도 하나 이상 선택되는 것이 바람직하다.In addition, in the mixing step may be constructed by further mixing the ocher, fluidizing agent.
